FIREPROOF PARTITION...

Specification of Letters Patent.

Patented Oct. 24, 1905.

l o all when), it may concern:

Be it known that we, CHARLES M. Dnrnw and Hours E. MCCOY, citizens of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Fireproof Partitions, of which the following is a specification.

Our invention relates to an improved fireproof building construction, and particularly pertains to a partition structure. Its object is to provide a simple, cheap, light, and stable rigid fireproof structure of this character.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 shows the application of my invention. Fig. 2 is a transverse section of a panel. Fig. 3 .is a perspective view of same. Fig. 4 is a detail of one of the anchor-plates 6.

In carrying out our invention we prefer to use slabs 0r panels, as A, in. our partitions in lieu of the usual concrete, plaster, and furring, employing suitable means to retain these slabs or panels in position. These slabs, blocks, or panels may be of any suitable size. For partitions, which are usually desired thin, the panels may be forty-eight inches by sixteen inches by two inches and have their opposite longitudinal edges provided with suitable means for making a tight joint when one panel is laid upon another, as shown in Fig. 1. The ends of the panels have a V-shaped groove at one end running in the direction of the width of the panel to receive the angle-iron studs or uprights 2, which form the end supports for the partition, while the opposite end of a panel has beveled edges to fit into the hollow of other angle-iron studs.

In practice where it is desired to set up one of our fireproof partitions a strip of iron 3 is secured to the floor along the line to be followed by the partition, and a corresponding channel-iron 4 is attached to the ceiling in the same vertical plane with strip 3. The latter and channel-iron 4 form respective top and bottom supports for the ends of the angleiron studs or uprights 2, and the channel 4 affords a slot for the lateral tongues 5 011 the topmost panels a to engage in. An angleiron stud or upright is first placed in position with one end resting on the floor-strip 3 and the upper end trimmed to fit the groove in the channel-iron 4. The foot of the upright is then secured against displacement by suitable means, as the anchor-plate 6, having a V-shaped notch to fit about the upright, the plate being fastened to the floor-strip by a screw. WVith an upright thus in position the panels or slabs A are laid one on another, with their recessed ends embracing and extending slightly beyond the extreme edges of the studs 2, so that when the cracks between the abutting ends of the panels or between the panels and the wall are closed the ironwork will be entirely incased and protected from fire and moisture. The ends and edges of the panels are tipped with a suitable quick-drying cement or plaster as they are put in, which fills all the interstices and allows the joints to be cleaned ofl fiush as the work progresses.

When a set of panels has been put in clear to the ceiling, the last panel. being slipped in between the next succeeding one and the channel 4, a second angle-iron stud is placed in position and suitably secured, the work proceeding where a long partition is needed as above described. If a door is desired in a partition of this character, a suitable frame is inserted, as shown in Fig. 1, consisting of a rough jamb 7, fitting the angle of the support 2 and projecting beyond each side of the paneling, an eighth of an inch or so, corresponding to the thickness of the wall-finish. A finished jamb 8, against which the door closes, is then fastened to the front of the amb-piece 7, the frame being completed by the finishin -strips 9.

The use of angle-iron uprights is advantageous over channels and other forms of supports because of their lightness, their unusual rigidity, their uniform straightness, and the interlock that their outside and inside angles afford with the fireproof panels.

In order to provide means for securing base-boards, wainscoting, moldings, and the like to the fireproof paneling, some of the panels may in the manufacture be molded around Wooden plugs 10, into which plugs nails may be driven. These plugs are placed at suitable intervals and preferably extend transversely through the panels to have their exposed ends flush with the sides of the panel. To prevent a plug being dislodged from the panel, as when a nail is being driven in, the plugs are provided with suitable anchor means, about which the material of the panel sets in the molding of the panel.

For convenience the plugs are here shown with an enlarged ortion intermediate of their ends, which en arged portion is so supported in the plaster of the panel as to prevent any longitudinal movement of the plug.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. A partition or wall construction comprising a vertical series of panels or blocks laid on edge and the uppermost panel or block provided with a tongue of reduced transverse diameter and top and bottom supports for the series of panels or blocks said top support including a channel-iron shaped to fit said tongue and having its edges resting upon the top of the panel at the base of the tongue and its sides substantially flush with the sides of the panel.

2. A partition or wall construction comprising a vertical series of panels or blocks having their adjacent surfaces provided with angular tongues and grooves, angle-iron uprights fitting said tongues and grooves, and

anchor foot-plates having the edges which are presented toward the uprights made an gular to fit said uprights said plates abutting the uprights horizontally, and a base-plate to which the anchor-plates are secured.

3. In a fireproof-partition construction, a panel or block provided with a transversely disposed wooden plug having its central portion made thicker than the ends whereby end pressure is resisted.

4. In a fireproof-partition construction the combination with a amb-timber having an angular tongue on one edge, of partition-panels having grooves on the edges adjacent to said timber, angle-iron uprights fitting the tongue of the timber and the grooves of the panels, means for anchoring the opposite ends of the panels, top and bottom supports for the series of panels, and finishing-strips secured to the timber.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
